amount of syrup that may pass through openings 30 may be regulated as desired. The flow of syrup may be entirely shut off by turning collar 33 downwardly until openings 30 are completely closed and inadvertent movement of the collar on screw 32 is eliminated by means of a helical spring 36 which surrounds the guide portion 31 and is adapted to be compressed within an annulus 38 formed between said guide 31 and collar 33.

The valve body 48 is of generally square shape and is bored and tapped at 4| to receive the aforesaid nut 21. Sufiicient clearance at 42 (Fig. however, is provided to efiect flow of syrup from openings 38 to the vertical bore 43 in the valve body. One side of valve body 40 is drilled horizontally to provide a bore 44 having a valve seat 45 at its inner terminus. The outer portion 46 of the bore 44 is tapped to receive a threaded cap 41, whereas the inner extremity of said bore 44 is countersunk at 48 and axially drilled to receive a valve stem 49. The countersunk portion 48 communicates with a vertical internal bore 58 through a diagonal passage 5| best seen in Fig. 9.

The valve 52 on the stem 49 has an annular gasket 53 adapted to abut the valve seat 45 and is retained on the valve stem 49 by means of peened washer 54. The opposite end of the valve stem 49 forms a spring guide 55 which is undercut at 56 to accommodate a valve spring 51. The cap 41 is internally bored at 58 to receive the opposite end of the spring 51 and is supplied with a gasket 59 to prevent leakage. It will be observed that this valve 52 controls flow of syrup from sump I8 to the bore 50 through openings 30 in nut 21, through bore 43 in the valve body 40, bore 44 in the valve body, and thence through passage 5| when valve 52 is open.

Referring now to Fig. '7, the construction of the carbonated water valve construction is generally similar to that of the syrup valve except that ingress of carbonated water under pressure to valve bore 44 is provided by means of a bore 60 in the coupling 6| which takes the place of the cap 41 and is provided with a gasket 59'. A valve sprin 51 also is provided which operates on the valve 52' in exactly the same manner as heretofore described in connection with spring 51 of the syrup valve 52. Carbonated water under pressure is supplied to the bore 60 by means of tubing 62 which is secured to coupling 6| by means of a t be nut 63. In order to prevent excessive discharge of the carbonated water. this coupling is provided with an orifice 64 which restricts the effective diameter of bore 59. The bore 44 in block or body 40 is counterbored to provide a seat 45' and is additionally counterbored at 65 to permit flow of the car bonated water through a passage 66 (Fig. 9) that is'drilled in the face of said counterbore 65. The valve 52 has a valve stem 49' and a retaining washer 54' positioned in the same manner as in the case of the syrup valve 52.

Referring now to Figs. 4 and 6, it will be observed that the valve body 40 has a downwardly extending annular flange 61 externally threaded to receive the internal threads provided on a conical nozzle 68 which terminates in an orifice 69 having radially extending teeth segments (Fig. 10) that are designed to break up and mix the syrup with the carbonated water.

A sleeve H (Fig. 6) is threaded at 12 in the bore 50 which is counterbored and tapped to provide a seat for the sleeve at 13. The bore of the sleeve H is thus aligned with the bore 50 in 4 block or body 40. An annular cup 14 is provided adjacent the upper end of the sleeve 1| so that the vertical passage 15 which communicates with passage 66 is in register with the annulus in the cup 14. The beveled edge 16 of the cup 14 imparts a swirling motion to the carbonated water ejected from the bore .15 as it is forced upwardly and out of the annulus of cup 14 and then downwardly around the sides of the cup which are provided with ample radial clearance with respect to the flange 61. 'The carbonated water is given further swirling motion by means of the tapered internal bore of the nozzle 68 where itis mixed with the syrup which flows from the outlet 11 of the sleeve 1| just in advance of the nozzle teeth 10. It will be apparent that the valve and nozzle construction provides no mixing of. the syrup with the carbonated water until just prior to discharge from the nozzle 88.

Referring now to the valve operating mechanism, a pair of cam elements and 8| are rotatably mounted by means of threaded bushings 82 and 83 in the body 4|] with their axes arranged at right angles to the axes of the valve stems 49 and 49'. The inner extremity of each cam element is provided with a cam surface adapted to be engaged by the tip of the associated valve stem and it will be noted that the surface 84 on the carbonated water cam 8| is constructed so that the valve 52 (Fig. '7) is closed in one position only of the cam 8|, whereas the surface 85 on the cam 80 (Fig. 5) is of greater arcuate extent, and arranged so that the valve 52 remains closed during approximately of movement of the cam. The outer extremity of each cam element is provided with lugs 86 and 86' which cooperate with grooves in the spaced opposed arms of a bracket 81 that are secured to the cam elements by means of screws 88. The bracket 81 is U-shaped and extends around valve body 48 as shown, being provided with an operating handle 89 secured thereto by a screw 90.

The bracket 81 is secured to the cam elements 80 and 8| so that in the horizontal position of the handle, shown in solid lines in Fig. 2 of the drawing, the rotational position of said cam elements 80 and 8| is such that the valves 52 and 52', respectively, are closed, and in the upper operative position of the handle, shown in dotted lines in Fig. 2, the valve 52 remains closed by reason of the elongated arcuate cam surface 85 provided on the associated cam element 89, and the other valve 52 is actuated to the open position, while in the lower operative position of the handle, also shown in dotted lines in Fig. 2, the rotational positions of the cam elements 8|) and 8| are such that both of the valves 52 and 52' are opened. Thus, in operation of the device, in the raised operative position of the handle, carbonated water only will be discharged from the nozzle while in the lower operative position of the handle both carbonated water and flavor syrup will be mixed together and discharged from the nozzle 69, and the amount of syrup discharged in proportion to the amount of carbonated water may be regulated as desired by adjusting the clearance between the collar 34 and the upper ends of the openings 3!! in the nut 21 as previously described.

From the foregoing it will be apparent that the present invention provides, a novel dispensing valve construction which is operable to control the flow of two fluids in predetermined proportions with respect to one another, and also includes the provision of a novel syrup container for use in conjunction with such a valve. The invention also provides a novel dispenser as set forth wherein the flow of one fluid therethrough may be adjustably regulated as desired with reference to the flow of the other fluid. The

invention further provides a novel device for dispensing flavored sodas wherein the flavor syrup is fed through the valve by gravity and the soda water is fed through a second valve under pressure, the two fluids subsequently being mixed together. Furthermore, the present invention provides a novel dispensing valve construction which is operable in one operative position thereof to discharge a mixture of both fluids, and in another operative position to discharge one of said fluids only.

While a particular embodiment of the present invention is illustrated and described herein, it is not intended that the invention be limited to such disclosure and changes and modifications may be made therein and thereto within the scope of the following claim.

We claim:

A device for dispensing apparatus for mixing carbonated water and syrup comprising a member having a depending annular flange defining a recess in the bottom wall of said member, outlet passages for each of the two fluids opening into said recess, an elongated discharge tube secured to said member and depending coaxially interiorly of said recess and having an axial bore therethrough communicating at one end with the outlet passage for the carbonated water, an annular cup coaxial with and substantially occupying said recess surroundin said tube arranged in registry with the outlet passage of the other fluid, said cup and the side walls of said recess operable to impart a swirling movement to the fluid discharged therefrom, a discharge nozzle releasably secured to the annular flange portion of said member and coaxially surrounding said discharge tube and cup, the outer end of said discharge tube terminating inwardly adjacent the outlet opening of the nozzle, and radially inward projecting elements circumscribing the nozzle outlet opening and operable to break up and -interrnix fluids discharged therethrough.
